I cried. I cried like a big dumb piece of shit.
I actually think it's the best out of the three. I approached this as a cash in and didn't really have high expectations. Oh, it's just the toys in another adventure, but it was so much more. As with most everything Pixar does it transcended the simple animated film genre. It starts out kind of basic but really gets going once the toys get to the daycare. After that it doesn't let up.
The funniest part was easily Ken modeling for Barbie. Also, I think my favorite character is the pig. His sarcasm kills me. I like Mr. Potato Head, too. I like all the abrasive characters.
That ending tho, wow, I teared up big time. Felt like an idiot.
